WINDING MECHANISM.

Specification of Letters Patent.

Patented Nov. s, 1908.

Application filed September 27, 1907. Serial No. 3%,812.

To all whom it may concern:

Be it known that 1, CHARLES WIEBKE, a citizen of the United States, residing in the borough of the Bronx, in the county of New York and State of New York, have invented a certain new and useful Improvement in Winding Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

The present invention relates particularly to textile machinery in which chenille, yarn, cord or other textile material is wound upon spools or reels, either as the express function of the machine or incidentally to some other operation performed on the material.

Heretofore, so far as the inventor is informed, when textile material has been wound upon a spool the coils of material have been applied directly to the body of the spool under more or less tension, and in order to distribute the material uniformly and fill the spool it has been necessary either to impart a compound movement to the spool and the material-delivering devices, so as to form elliptical coils arranged in inclined position on the spool, or to employ some kind of traversing mechanism for guiding the material from end to end of the spool.

The object of the present invention is to produce a winding mechanism by which a spool may be wound full from end to end by a simple rotation and without the use of traversing mechanism. This is accomplished by providing means by which coils are formed of a diameter substantially greater than the body of the spool, and these coils are then delivered loosely to the end of the spool, so that they form a loose mass and fill it from end to end under the influence of gravity or the pressure of succeeding coils, being moved freely along the spool owing to their looseness.

The invention consists, therefore, in its broadest aspect, in winding mechanism provided with a spool and with means for forming and delivering coils of greater diameter than the spool.

More specifically, the invention comprises a coil guide comprising an inclined portion operating to move the coils longitudinally with respect to the spool, and a coil-gaging portion operating to fix the diameter of the coils and formed to make the coils of substantially greater diameter than the spool body so that they will rest loosely thereon.

Other and minor features of the invention will be referred to in connection with the description of the illustrated embodiment of the invention.

I will now describe the embodiment of my invention illustrated in the accompanying drawings, and will thereafter point out the invention in claims.

In the drawings Figure 1 is a front elevation of a twisting machine embodying the invention. Fig. 2 is a horizontal section showing the lower portion of the machine and the actuating mechanisms for the spools. Fig. 3 is an enlarged elevation, partly in section, showing the upper end of a spool and the flier cooperating therewith. Fig. 4 is, a detail plan view of one of the coil guides.

The spool of the present invention is adapted for use in various machines in which textile materials of different charac ter are wound, but in the drawings the invention is illustrated as embodied in a che nille-twisting machine. The machine has four spools 1 journaled vertically in a frame 2. Each spool comprises four rods 3 forming the body upon which the chenille is wound, and these rods are fixed at their ends in upper and lower heads 4: and 5 respectively. The lower heads 5 are centered on studs 6 and seated on plates 7 journaled on the studs, the heads and the plates 7 being rotatively connected by pins 8 fixed in the plates and loosely engaging corresponding openings in the spools. The plates 7 are connected through frictional connections 9, with pulleys 1O journaled on the studs 6. The pulleys 10 are connected, by belts 11, with a larger driving pulley 12. The pulley 12 is fixed on a' vertical driving shaft 13 journaled in the frame 2 and connected, through gearing 14, with a suitable source of power. By these means the spools are rapidly rotated to impart the necessary twist to the chenille.

The upper heads 4 are centered on sleeves 15 slidable vertically on hollow shafts 16 journaled at the top of the frame 2. The sleeves 15 and the form of connections above described at the lower ends of the spools are adapted to permit the ready removal and replacement of the spools. To remove a spool it is raised to disengage it from the stud 6 and the pins 8. The sleeve 15 is then raised by means of finger pieces 19 until it is clear of the head l, and 'thus space is provided between the head and the shaft 16 sufficient to permit the lower end of the spool to be swung laterally out of the ma chine so that the head s may be withdrawn from the shaft 16. A flange 18 on the lower end of the shaft 16 prevents the sleeve 15 from falling off when the spool is removed, and a collar 17 on the upper end of the shaft sustains the shaft vertically. The chenille passes down the hollow center of the shaft 16 from its upper end, and emerges from a lateral opening 21 (Fig. 3). The chenille then passes through a hollow arm 22 fixed to the shaft 16 and forming a flier from which it is delivered to the spool. Each flier comprises a pair of arms 22, to secure proper balance, though only one arm is used at a time. To rotate the flier-a pulley 23 1s fixed to the shaft 16 and connected, by a belt 24, with a large pulley 25 on the driving shaft 13. The relative rates of rotation of the spool and the flier are so adjusted, by properly proportioning the driving pulleys, that while the spool and the flier have both a rapid rotation in the same direction to twist the chenille, they have a comparatively slight differential movement suflicient to cause the chenille to be wound on the spool as fast as it is twisted sufficiently.

In the mechanisms described above the arrangement is such that the chenille is all delivered to the spool at its upper end, and the device by which the chenille so received is distributed automatically throughout the length of the spool so as to completely fill it will now be described. Upon each rod 3 is mounted, at its upper end, a coil-guiding device by which this is accomplished. Each coil-guiding device comprises an open-sided body 26 and a set screw 27 by which it is fixed to one of the rods 3. An outwardlyinclined arm or coil-receiving member 28 mounted on the body 26 receives the chenille from the flier arm 22, and is beveled at one side, as shown in Fig. 8 and at 29 in Fig. 4, to afford a smooth surface for this purpose. Below the coil-receiving portion is a short portion 30 substantially parallel to the axis of the spool, hereinafter designated as the coil-gaging portion, and below this is an inclined coil-delivering portion 31 connecting the coil-gaging portion with the body of the spool.

The coil guiding devices operate as follows: As each coil is delivered, under a tension controlled by the friction coupling 9, to the coil-receiving members 28, it tends to slide down, owing to the inclination of these members, to the coil-gaging portions, and thus as the coils accumulate they are gradually forced in a series down the coil guides to the body of the spool. In order that the coils so delivered to the spool may pass down freely and fill the spool it is necessary that they be somewhat greater in diameter than the body of the spool so as to be loose there on, and this result is accomplished by the coil-gaging portions 30. These are of sufficient length to hold several coils, and the friction of the coils thereon is enough to prevent slack from being drawn back from the coils as they are delivered to the spool body by the coil-delivering members 31, but not enough to substantially impede the downward movement of the coils on the coil guides under the influence of the inclined coilreceiving members. In this manner a final diameter slightly greater than that of the body of the spool is imparted to each coil before it is delivered to the spool, and the coils pass freely down the spool under the influence of gravity and the pressure of succeeding coils until the spool is full from end to end. The coil delivering portions 31, while not essential to the action above described, improve the operation of the coil guides by causing the coils to be delivered uniformly in horizontal position and regular form to the spool body.

Various modifications may be made in the construction and operation of the illustrated embodiment of the invention within the na ture and scope of the invention as defined in the following claims.
